Alaei, Mohammad (Date of defense: 2013-06-27)
In Wireless Multimedia Sensor Networks (WMSNs) the lifetime of battery operated visual nodes is limited by their energy consumption, which is proportional to the energy required for sensing, processing, and transmitting ...
Nishtala, Rajiv (Date of defense: 2017-07-10)
In 2013, U.S. data centres accounted for 2.2% of the country's total electricity consumption, a figure that is projected to increase rapidly over the next decade. A significant proportion of power consumed within a data ...
AlSkaif, Tarek (Date of defense: 2016-07-26)
The need for energy conservation, grid reliability, and improved operational efficiencies have led to the changes from conventional electricity grids which have “blind” and manual operations, along with the electromechanical ...
Silfa, Franyell (Date of defense: 2021-01-25)
Deep Learning algorithms have been remarkably successful in applications such as Automatic Speech Recognition and Machine Translation. Thus, these kinds of applications are ubiquitous in our lives and are found in a plethora ...
Arnau, Jose Maria (Date of defense: 2015-04-24)
The design of mobile GPUs is all about saving energy. Smartphones and tablets are battery-operated and thus any type of rendering needs to use as little energy as possible. Furthermore, smartphones do not include sophisticated ...
Spadaro, Salvatore (Date of defense: 2005-02-15)
La arquitectura de las redes de transporte actuales está basada en la tecnología de transporte SDH (Synchronous Digital Hierarchy). Las redes SDH se han diseñado y están optimizadas básicamente para el transporte del tráfico ...
Mahdavi, Kaveh (Date of defense: 2022-07-28)
Clustering analysis is widely used to stratify data in the same cluster when they are similar according to the specific metrics. We can use the cluster analysis to group the CPU burst of a parallel application, and the ...
Hundessa Gonfa, Lemma (Date of defense: 2003-04-03)
Multiprotocol Label Switching (MPLS) fuses the intelligence of routing with the performance of switching and provides significant benefits to networks with a pure IP architecture as well as those with IP and ATM or a mix ...
Kestor, Gökçen (Date of defense: 2013-03-22)
Chip Multithreading (CMT) processors promise to deliver higher performance by running more than one stream of instructions in parallel. To exploit CMT's capabilities, programmers have to parallelize their applications, ...
Fernández Díaz, Gabriel Alejandro (Date of defense: 2018-11-15)
Artificial system interaction with the real environment is in general based on the deployment of properly coordinated sensors and actuators, establishing between them a “dynamic control-loop”. The time to close this ...
Meseguer Pallarès, Roc (Date of defense: 2012-03-02)
In collaborative learning scenarios, the use of computers and communication networks to facilitate collaboration is becoming popular, the Computer-Supported Collaborative Learning (CSCL). In face-to-face CSCL scenarios, ...
Otero Calviño, Beatriz (Date of defense: 2007-04-13)
En este trabajo estamos interesados en realizar simulaciones numéricas basadas en elementos finitos con integración explícita en el tiempo utilizando la tecnología Grid.<br/>Actualmente, las simulaciones explícitas de ...
Solé Pareta, Josep (Date of defense: 1991-05-17)
Las contribuciones principales del trabajo realizado en esta tesis son: 1) estudio de la influencia del grado de rafagueo (burstiness) del trafico en el comportamiento de los dispositivos que integran una red ATM, 2) ...
Subotic, Vladimir (Date of defense: 2013-07-26)
Parallel programming is used to partition a computational problem among multiple processing units and to define how they interact (communicate and synchronize) in order to guarantee the correct result. The performance that ...
Asifuzzaman, Kazi (Date of defense: 2019-07-29)
It is questionable whether DRAM will continue to scale and will meet the needs of next-generation systems. Therefore, significant effort is invested in research and development of novel memory technologies. One of the ...
Chronaki, Kallia (Date of defense: 2018-11-21)
Asymmetric multi-cores (AMCs) are a successful architectural solution for both mobile devices and supercomputers. These architectures combine different types of processing cores designed at different performance and power ...
Sánchez Barrera, Isaac (Date of defense: 2022-04-06)
The end of Dennard scaling has caused a stagnation of the clock frequency in computers.To overcome this issue, in the last two decades vendors have been integrating larger numbers of processing elements in the systems, ...
Anglada Sánchez, Martí (Date of defense: 2020-06-09)
The computation capabilities of mobile GPUs have greatly evolved in the last generations, allowing real-time rendering of realistic scenes. However, the desire for processing complex environments clashes with the ...
Sequeira, Diogo Gonçalo (Date of defense: 2022-10-31)
(English) Optical communications have been extensively investigated and enhanced in the last decades. Nowadays, they are responsible to transport all the data traffic generated around the world, from access to the core ...
Jaulmes, Luc (Date of defense: 2019-06-21)
Hardware errors become more common as silicon technologies shrink and become more vulnerable, especially in memory cells, which are the most exposed to errors. Permanent and intermittent faults are caused by manufacturing ...
